SPECIFICATION forming* part 0f Letters Patent No. 667,521, dated.February 5, 1901. Application liled July 25, 1900. Serial No. 24,753.(No model.)

To @ZZ whom t may con/cern.'

Be it known that I, CHARLES HILL, a citizen of the United States,residing in Paterson, in t he county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Blind Catches andLocks; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

This invention relates to fasteners adapted to secure blinds or shuttersin either an open or a closed position; and it has referenceparticularly to that class of such devices which are provided with meanswhereby to lock them when holding the shutter or blind closed, so thatthe latter cannot be opened from the outside.

The invention consists in the improved shutter-fastener and in thecombination and arrangement of its various parts, substantially as willbe hereinafter pointed out, and nally embodied in the clauses of theclaim.

In the accompanying drawings,wherein corresponding letters of referencedesignate like parts, Figure l is a perspective view of a portion of awindow, showing my improved shutter-fastener in operative position. Fig.2 is an enlarged sectional view of substantially what is shown in Fig.l, my improved shutter-fastener being shown in elevation. Fig. 3 is aview, partly in section and partly in plan, of my improvedshutter-fastener, certain parts being removed. Fig. 4C is a transversesectional view of the shutter-fastener on the line a; in Fig. 2. Fig. 5is a view substantially similar to Fig. 2, but showing a modified formof my improved shutter-fastener. Fig. 6 is a view in side elevation ofanother modified form ofthe shutter-fastener, one member of the casingbeing removed. Fig. 7 is a transverse sectional view on the line y y inFig. 6, and Fig. 8 is an end View of a certain two-part tubular casingin which the movable parts of the fastener are arranged and which isadapted to be secured in the shutter.

In the accompanying drawings, o. designates the frame of the window, andb denotes one of the blinds, the same being hinged therein at one sidein the usual manner. In the lower portion of the frame of the shutter isformed an aperture c, into which fits a longitudinallydivided tubularcasing d. The members of this casing may be secured together by pins e,having their ends riveted, and in order to prevent the casing fromworking loose out of the shutter-frame it may be provided withsurrounding corrugations or screw-threads f. If sere w-threads areprovided, a substantially rectangular projection g, extending from theinner end of the casing, will afford a hold for a wrench whereby toscrew the casing into position.

There are preferably two of the pins e. On the outer one is pivoted ahook h, while on the'inner one is pivoted another hook e', the formerbeing adapted to engage the usual staple or other catch on the outsideof the building, near the window-frame, and the latter being adapted toengage the catch j, which is ordinarily secured on the bottom rail ofthe window-frame. These hooks are provided at their adjacent ends withintermeshing toothed segments k, so that when one is manipulatedmovement will be imparted to the other. If desired, the hook h may beprovided with a rollerl, which facilitates its automatically engagingthe outside staple when the blind is thrown open. The hook i eX- tendsthrough a rectangular orifice m, which is `formed in the projection g.

The top edge of the body of the hook i is substantially fiat, andthereon is arranged a block in the form of a wedge n, which is providedwith a dovetailed projection o, adapted to engage a corresponding slotp, formed in the bodyof the hook. The reduced or tapering end of theWedge is adapted to enter between the upper edge ofthe hook and the topof the opening m when the hook is in the position in which it appears inthe drawings, and in order to normally draw it into this p0- sition aspiral spring q, arranged in the slot p and connecting the projection 0and the inner end of the hook t', as best shown in dotted lines in Fig.l, is provided. In order that the projection 0 may be introduced intoIOO tion that the roller-Z and the spring q are eliminated.

In both the forms of the device already described it is preferred thatthe bottom of the slot p be slightly deeper at its rear end than at apoint in the bottom thereof which is opposite the set-screw when thewedge is forward. Thus the set-screw may be screwed down into thedepression thus formed far enough so as to effectively hold the wedgeback, but not necessarily so far as to bind it and make it difficult tosubsequently unscrew it.

In the modification shown in Fig. 6 instead of providing two hooks eachadapt-ed to have an overengagement with its respective staple or catchthe two hooks are made as one.

tdesignates a lever which serves as a shank for the hooks u, and c, theformer being adapted to engage the catch j on the window-frame, havingan overengagement therewith, and the latter being adapted to engage theoutside staple, with which it has an undercugagement. The lever ispivoted upon the pin e, in this case there being only one of said pins.The lever carries the wedge n, which, as in the case of the devicesalready described, has the dovetailed projection (o) and slot (p)engagement with the shank t. On the lower end of the screw s, which isalso provided in this case, being arranged in the wedge n, is swiveled asmall cross-piece w, which is movable in a longitudinal opening z,formed in the shank and communicating with the slot. Near its ends theopening is provided with depressions or recesses a', with either ofwhich the cross-piece is adapted to engage to hold the wedge in eitherof its limits of motion when the screw has been secured to draw thecross-piece into the recess.

It is thought that the manner of manipulating the device will be obviouswithout further description.

It should be remarked that although my invention is particularlyapplicable to that class of shutter-fasteners which are so con-Ystructed that they are capable of being locked to obviate manipulationfrom the outside, nevertheless by virtue of the fact that the hooks ofmy device have intermeshing teeth it can be made use of Where it isdesirable that it be operative from both the inside and the outside.

Having thus fully described my invention,

` what I claim as new, and desire to secure by l. In a shutter-fastener,the combination of a casing adapted to be arranged in the shutter, andhooks having intermeshing teeth and pivoted in said casing, one of saidhooks being adapted to engage the outside catch and the other of saidhooks being adapted to engage the inside catch for said shutter,substantially as described.

2. In a shutter-fastener, the combination of a casing adapted to bearranged in the shutter, hooks having intermeshing teeth and pivoted insaid casing, one ot said hooks being adapted to engage the outside catchand the other of said hooks being adapted to engage the inside catch forsaid shutter, and means for locking one of said hooks against actuation,substantially as described.

3. In a shutter-fastener, the combination of a casing adapted to bearranged in the shutter, hooks having intermeshing teeth and pivoted insaid casing, one of said hooks heilig adapted to engage the outsidecatch and the other of said hooks being adapted to engage the insidecatch'for said shutter, and a sliding element carried by one of saidhooks and adapted to be interposed between the same and the casing tolock said hook against actuation, substantially as described.

et. In a shutter-fastener, the combination of a casing adapted to bearranged in the shutter, a hook pivoted in said casing and adapted toengage a suitable stationary catch, said hook having a depression, asliding block carried by said hook and adapted to be interposed betweenthe saule and the casing to lock said hook against actuation, and` asecuring device for said block, said device being adapted to engage saiddepression, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this19th day of July, 1900.

CHARLES HILL.
